What does Btu (IT)/hour/square foot measure?

It measures the rate of heat transfer per unit area, specifically one British thermal unit transferred per hour across one square foot of surface.

When should I use erg/hour/square millimeter?

This unit is used for reporting very small-area heat transfer, such as in laboratory thin-film testing or microelectronic thermal characterization using CGS units.

Why is this conversion important?

It allows translating heat flux density values between unit systems used in building energy analysis and those used in precise small-scale or CGS-based experiments.
